Massive Carbon Storage Found in Arctic's City-Sized Logjam

Scientists have mapped a 51-square-kilometer pile-up of fallen trees and ancient wood in the Mackenzie River Delta in Nunavut, Canada, which is the largest "logjam" in the world. The researchers used high-resolution satellite imagery and deep learning artificial intelligence to map this vast wood deposit. The logs in the Mackenzie River Delta store about 3.4 million tons of carbon, which is a significant quantity, even on a global scale. The pile-up is likely to be having a massively underappreciated impact on the planet's carbon cycle, as logjams like this are often ignored when it comes to their impact on the wider environment.
